that may be absorbed but a wooden pole. A structural engineer must

be consulted for detailed structural requirements. Poles intended for

planting in the ground must be purchased at required lengths, Never

South African Wood Preservers Association (SAWPA)

The South African Wood Preservers Association (SAWPA) is a

non-profit association formed in 1980, by the South African wood

preserving industry, primarily to promote timber treatment and

are not durable. By applying the correct chemicals to these timbers

ensures that the timber performs as if it were durable thereby

giving predictable long life performance.
